DescriptionThe main criteria in assessing the adaptive capacity of Actinidia deliciosa (kiwi), cultivated in Russian subtropics were yield of the introduced cultivars, as well as ecological (stability and periodicity of fruiting) and biological indicators (resistance and periodicity of fruiting). The studied nature of the way Actinidia cultivars react to the constantly changing weather conditions during the period from 1998 to 2011 will help to optimize the placement of the crop in subtropical zone, and use natural resources for its unique climatic properties of Russian territory in a sustainable way

ECOGEL IS THE NEWEST COMPLEX OF WATER SUPPLY FOR FRUIT PLANTS
06.00.00 Agricultural sciences
DescriptionFrom 2011 to 2015 in the laboratory conditions there were studied the physical properties of absorbents in the controlled environment. There was defined that in the variant of the "soil+water" the usual colloidal mass is formed and in variants "soil+absorbents+water" - a mixture of soil and gel. There was determined that the least diurnal evaporation was fixed at the use of the mixture: soil+ preparation “Ecogel-1”. In the control variant of the experiment the full water evaporation was marked on 31st day after beginning of the experiment, in the variant with the use of the absorbent Aqua Life the whole water evaporated on 48th day, and at the use of preparations Ecogel-1 and Ecogel-2 the duration of evaporation of the same amount of water supply at temperature 22-24оС and air moisture in 55-60% continued 57-65 days. In the result of five-year laboratory researches there was determined the possibility of development of water-saving technology for fruit plantations. When we used absorbents (granules, powders) in planting process and watering resulting the gel-like mass completely collapses the root system of fruit plants and the operation of the system "soil-roots-leaves" will not depend on the physical condition of soil and environment due to water consumption for transpiration

EKOBENTOKORM - NATURAL SORBENTS
06.00.00 Agricultural sciences
DescriptionPoultry farming is characterized by a relatively low cost of production, so it is more cost-effective compared with other sectors of animal husbandry. However, the feed of plant and animal origin used in the poultry industry does not always correspond to the requirements of biological safety and are subject to damage by fungi producing mycotoxins, causing extensive economic damage. Therefore, to improve the performance of the cultivation of chickens broilers was used natural sorbent - ekobentokorm (from the local cheap raw materials - bentonite clay), which is not only a source of macro - and microelements, but also with adsorptive activity in respect to mycotoxins, endotoxins, salts of heavy metals and pathogenic microflora, improves digestion and metabolism

WOOL PRODUCTIVITY OF MERINO SHEEP OF IMPROVED GENOTYPES
06.00.00 Agricultural sciences
DescriptionThe article deals with the issue of improving the profitability of sheep breeding by using improved mutant genotypes in the breeding system. The results of studies of the main indicators of economic-useful traits are given, the dynamics of growth, level and quality of wool productivity of sheep of improved genotypes obtained on the basis of such breeds as Soviet merino and Stavropolskaya, as well as firstgeneration daughters cultivated in themselves are estimated. It was found that at birth, the live weight in the groups of the 3 group (the breeding of half-blooded hybrids "in oneself") was higher than that of the females from the 1 and 2 groups, respectively, by 0.50 kg, or 13.1%, and by 0.20 kg or 5.2% (P> 0.95). At a more senior age, the young, having a large live mass at birth, retained its rank position. The highest indicator of the cutting of physical wool was observed in animals of the 2 group, obtained as a result of the use of sheepproducers of Stavropolskaya breed on sheep of the Soviet merino. The parameters of the 1 and 3 group were lower by 0.6 kg - 12.3% and 0.17 kg - 3.5% (P> 0.95), respectively. The conclusion is made that the use of sheep-producers of the Stavropolskaya breed on the uterus of the Soviet merinos breed had a positive effect on the wool productivity and the live weight of the hybrid offspring. Further breeding of half-blooded hybrids “in oneself” showed the possibility of reproducing improved genotypes without losing the acquired qualities

DescriptionThe article comprises the results of two research-and-production experiments with meat poultry and pigs grown on local forages including biologically active preparations. The purpose of the research was to study the effect of enzyme preparations Cellolux-F and protosubtilin G3x and probiotic feed additive “Sporotermin” on the intensity of growth, development and metabolic processes, and conversion of rations nutrients into production. The results of the research showed that to improve the physiological and biochemical status and intensity of metabolic processes in the body, and also improving the conversion of feed nutrients into products in composition of chickens and pigs’ mixed feed one should feed the mixture of enzyme preparations Cellolux-F and protosubtilin G3x with probiotic feed additive “Sporotermin”

ECONOMIC-BIOLOGICAL FEATURES AND EXTERIOR MAINTENANCE OF YOUNG CATTLE IN THE KRASNODAR REGION
06.00.00 Agricultural sciences
DescriptionIn the Krasnodar region there is a unique gene pool of animals both for dairy and meat. To assess the heifers the authors formed five experimental groups of animals, the most common species in the region. The authors studied the main economic, biological and exterior features: live weight, measurements, assessment of the exterior. The studies found that among intensive species with the largest body weight throughout the growing period, in 8-month old Charolais heifers superior Simmental ones at 17.4 kg. In one year old Simmental heifers were 9.2 kg (R˂0,05) ahead of Charolais and in 15 months – 10 kg (R˂0,05). Over the entire period of growth the highest rates of relative growth rates of heifers were obtained by red steppe breed type named Kuban, which had an advantage over the Aberdeen-Angus – 19.1%, Charolais – 5.6%, Hereford – 6.2%, and the difference between them and Simmental weren’t fixed. When growing, the animals become less tall, more stretched, wide and massive. We have noted that during the period of cultivation we had increased indices: stretch (9% – Red Steppe, 13.8% – Charolais, 16.1% – Hereford); chest (5.4% Aberdeen Angus). This reduces the index of long legs of red steppe – 5.6%, 10.9% for Charolais. The study of linear growth of animals confirms that the animal meat breeds of live weight increase was due to the extension of the body and increase the width of the pelvis and chest. Some different facts were observed in heifers of Red Steppe breed. For them, the most characteristic increase in the width of the chest was 1.44 times, as well as increasing the depth of the chest and chest girth behind the shoulders
